Description

  The present invention relates to a data editing method, a data editing program, and a data editing apparatus.

  Conventionally, when wiring is performed by electric CAD (Computer Aided Design), editing is performed in units of nets indicating connection of wiring from pin to pin of a component. The pin is not limited to the component pin, and includes a plated hole for changing the wiring layer.

  In wiring editing by electric CAD, various wiring paths are often examined due to noise problems and wiring routing problems. In this case, it is common to use an UNDO function such as “edit”-“restore” to arbitrarily restore the wiring under consideration up to the point in time. Note that the method of restoring edited contents using the UNDO function during editing work is not limited to electric CAD, and is used in various fields such as document creation software and spreadsheet software.

  However, in the conventional technique, when editing is resumed after restoring data being edited at an arbitrary time, there is a problem that the restored data cannot be restored to the data before restoration.

  For example, the above problem will be described by taking the document creation software shown in FIG. 24 as an example. FIG. 24 is a diagram for explaining the prior art. As shown in FIG. 24, a device that executes document creation software (hereinafter referred to as a character input device) accepts a user input operation and inputs characters “A”, “I”, “U” in order into a predetermined area. To do. Subsequently, when receiving a UNDO operation from the user, the character input device deletes the last input “U”. Subsequently, the character input device receives an editing operation again from the user, and inputs the received “e” next to “a” and “i”. In other words, “A”, “I”, and “E” are input in this order.

  Thereafter, when the character input device accepts an UNDO operation from the user, the character input device deletes the last input “e”. Further, when an UNDO operation is accepted from the user, the character input device deletes “I” input before “E” deleted by the previous UNDO operation.

  In other words, when the editing is resumed after the deletion of “u” is executed by the first UNDO operation, the character input device is in a state before the data editing is resumed, “A”, “I”, “U”. ”Cannot be restored.

  The disclosed technology has been made in view of the above, and even when editing is resumed after restoring the data being edited at an arbitrary time, the restored data can be restored to the data before the restoration. An object is to provide a data editing method, a data editing program, and a data editing apparatus.

  Hereinafter, embodiments of a data editing method, a data editing program, and a data editing apparatus disclosed in the present application will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

[Data editing device configuration]
FIG. 1 is a block diagram illustrating the configuration of the data editing apparatus according to the first embodiment. The data editing apparatus 10 shown in FIG. 1 processes various data such as CAD (Computer Aided Design) data such as circuit boards, parts, and wiring, document input, spreadsheets, etc., and executes data editing such as update and restoration of each data. To do. In the first embodiment, an example in which the data editing apparatus disclosed in the present application is applied to an electric CAD apparatus that processes CAD data will be described. However, it is built in a computer apparatus that executes software for processing document input, spreadsheet, and the like. Also good.

  As shown in FIG. 1, the data editing apparatus 10 includes a communication control I / F unit 11, an input unit 12, a display unit 13, a storage unit 14, and a control unit 15. The communication control I / F unit 11 is an interface having at least one communication port, and controls information exchanged with other devices. For example, the communication control I / F unit 11 receives data to be edited and transfers it to the control unit 15.

  The input unit 12 is, for example, a keyboard, a mouse, a microphone, and the like. The input unit 12 receives inputs such as an edit start instruction, an edit end instruction, and an UNDO operation from the user, and inputs them to the control unit 15 and the like described later. The input unit 12 can read information from and write information to a storage medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a magnetic disk. For example, the input unit 12 reads a file or the like to be edited from the storage medium and transfers it to the control unit 15.

  The display unit 13 is, for example, a monitor, a display, a touch panel, a speaker, and the like, and displays and outputs a data editing result performed by the control unit 15 described later, data being edited, and the like. The display unit 13 to be described later realizes a pointing device function in cooperation with the input unit 12.

  The storage unit 14 is a storage device such as a semiconductor memory device such as a RAM (Random Access Memory), a hard disk, or an optical disk, and stores data and programs necessary for various processes performed by the control unit 15. Further, the storage unit 14 stores the data when the control unit 15 issues a save request to the data being edited.

  The storage unit 14 stores, as UNDO information (execution information), edited contents indicating the edited contents of data or restored contents indicating the restored contents in time series in which editing or restoration is performed. Furthermore, for example, in the case of electric CAD, the storage unit 14 may store an editing portion indicating where the editing or restoration has been performed, such as the net A or the component A, in association with the execution information.

  Here, the example of the information which the memory | storage part 14 memorize | stores is demonstrated using FIG. 2 and FIG. FIG. 2 is a diagram illustrating an executed editing example, and FIG. 3 is a diagram illustrating an example of information stored in the storage unit. FIG. 3 shows information stored when the editing shown in FIG. 2 is performed. In addition, here, as an example in which wiring and component placement changes are performed as data editing by electric CAD, an example will be described in which data editing is performed for each net unit indicating a wiring connection from pin to pin of a component, for example. .

  Specifically, as shown in FIG. 2, in this example, editing 1, editing 2, editing 3, and editing 4 are sequentially performed on the CAD data to be edited. In edit 1, editing for net A and editing for part B are executed. Similarly, in editing 2, editing for net C, editing for net D, and editing for part E are executed. In edit 3, editing for net F, editing for component E, and editing for net D are executed. Similarly, in editing 4, editing for net F and editing for net C are executed.

  When such data editing is executed, as shown in FIG. 3, the storage unit 14 associates “UNDO information” and “object information” as information used when returning the executed operation. Remember. The “UNDO information” has “command information management” and “process information management” as management units, and is a management unit for managing the entire contents of data editing. That is, the storage unit 14 stores UNDO information as one “UNDO information” for each piece of CAD data (one file) for which editing has been executed.

  “Command information management” manages one piece of execution information, and stores data editing contents for each of editing 1 to editing 4 in FIG. 2, for example. “Process information management” is used to manage the processes that make up the execution information stored in “command information management”. "Object information". “Editing information” stores editing details such as wiring addition and component movement. For example, when “add wiring” is executed as “edit information”, “object information” indicates “status” indicating whether or not the wiring added by the wiring addition is a display target of the display unit 13 or the like. Remember. “Status” stores “normal” when displayed on the display unit 13 as data, and “deleted” when not displayed. For example, the contents actually executed such as how much the component B is moved in which direction and how the wiring between the component A and the component B of the net A is changed are stored in association with “command information management”. Alternatively, it may be stored as another database.

  For example, as illustrated in FIG. 3, the storage unit 14 stores edit 1 as “command information management”, and stores “edit information = wiring addition” regarding net A of edit 1 as “process information management”. Then, the storage unit 14 stores “wiring information status = normal” as “object information” of “post-edit information”. In the case of this example, in the edit 1, it is shown that the wiring is added to the net A, and the added wiring is displayed in the CAD data being edited.

  In addition, the storage unit 14 stores edit 1 as “command information management”, and stores “edit information = part movement” regarding the component B of edit 1 as “process information management”. Then, the storage unit 14 stores “part information status = deletion” as “object information” of “pre-edit information”, and “part information status = normal” as “object information” of “post-edit information”. Remember. In the case of this example, the editing 1 indicates that the part B is moved and displayed in the CAD data being edited. The “status” of the pre-edit information is “deleted”. For this reason, it can be seen that the data before the movement of the part B moved by the editing 1 is not displayed in the CAD data being edited, and the data after the movement is displayed in the CAD data being edited.

  Each editing need not be executed continuously. For example, after executing editing 1, the CAD data being edited is saved and the editing ends. Thereafter, even if the file is reopened and editing 2 is executed, the same CAD data is edited. As a result, Edit 1 and Edit 2 are managed with the same “UNDO information”.

  Returning to FIG. 1, the control unit 15 is, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an electronic circuit such as a CPU or an MPU (Micro Processing Unit). The control unit 15 has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and required data. Furthermore, the control unit 15 includes an editing execution unit 16 and a restoration execution unit 17, and executes various processes using these.

  The editing execution unit 16 executes data editing, and stores the executed editing content in the storage unit 14 as UNDO information. For example, when the editing execution unit 16 receives editing contents such as wiring addition or component movement via the input unit 12 for CAD data to be edited on the data editing apparatus 10, the editing execution unit 16 displays the received editing contents. The process is executed on CAD data, and the executed contents are stored in the storage unit 14.

  As an example, it is assumed that the edit execution unit 16 receives an edit X for executing the movement of the part X after the edit 4 shown in FIG. In this case, the editing execution unit 16 moves the CAD data component X to be edited to a position designated by the user via the input unit 12. Then, the editing execution unit 16 adds “edit X” as “command information management” of “UNDO information management” of the CAD data stored in the storage unit 14. Further, the editing execution unit 16 adds “process information management, editing information = part movement” to the added “command information management = edit X”. Further, the edit execution unit 16 adds “part information, status = deletion” to “pre-edit information” of the added “process information management, edit information = part movement”, and “part information, Add "Status = Normal". It should be noted that the content actually executed such as how much the component B is moved in which direction is stored in association with “command information management”. As a result, the data editing apparatus 10 displays the component X moved by the new editing on the CAD data being edited displayed on the display unit 13 or the like.

  Further, when the editing execution unit 16 further edits the information already stored in the storage unit 14, it is not necessary to newly add “process information management”. “Management” may be updated. For example, it is assumed that editing for further moving the component B managed by the “process information management” of the net B shown in FIG. In this case, the editing execution unit 16 changes “part information and status” of “pre-edit information” in “process information management” of the part B shown in FIG. Change “Parts Information, Status” to “Normal”. Then, the editing execution unit 16 adds “edit X” as “command information management” of “UNDO information management” of the CAD data stored in the storage unit 14. Thereafter, the editing execution unit 16 manages the added “edit information” “command information management” and the changed component B “process information management” in association with each other. As a result, the editing information can be managed without creating new information, so that the storage capacity can be reduced.

  The restoration execution unit 17 includes an UNDO target determination unit 17a, an UNDO information control unit 17b, an UNDO execution unit 17c, and a REDO information addition unit 17d. When restoring the CAD data being edited, the restoration executing unit 17 having these functional units, when the information immediately before the latest UNDO information stored in the storage unit 14 is the edited content, Restore the data before the execution. In addition, when the information immediately before the latest UNDO information stored in the storage unit 14 is the restoration content, the restoration execution unit 17 restores the data before the execution of the restoration content. Then, the restoration execution unit 17 stores the restoration contents executed in this way in the storage unit 14 as UNDO information.

  The UNDO target determination unit 17a receives an UNDO process start and a processing target via the input unit 12, and determines a target to be restored. For example, when only the UNDO processing start instruction is received via the input unit 12, the UNDO target determination unit 17a outputs only the UNDO processing start instruction to the UNDO information control unit 17b. Further, the UNDO target determination unit 17a accepts the net A and the component B as the UNDO target together with the UNDO processing start instruction via the input unit 12, and sets the received processing target such as the net A and the component B to the UNDO information control unit. To 17b.

  When the UNDO information control unit 17b receives only an UNDO processing start instruction from the UNDO target determination unit 17a, the UNDO information control unit 17b reads the information immediately before the latest UNDO information stored in the storage unit 14 and outputs the information to the UNDO execution unit 17c. To do. In addition, when the UNDO information control unit 17b receives an UNDO processing start instruction and a processing target from the UNDO target determination unit 17a, the UNDO information control unit 17b is executed the latest among the execution information related to the processing target stored in the storage unit 14. The UNDO information is read out and output to the UNDO execution unit 17c.

  The UNDO execution unit 17c executes the UNDO information received from the UNDO information control unit 17b. For example, when the UNDO information received from the UNDO information control unit 17b is the editing content, the UNDO execution unit 17c restores the data before the editing content is executed. In addition, when the UNDO information received from the UNDO information control unit 17b is the restoration content, the restoration execution unit 17 restores the data before the restoration by the restoration content. Then, the UNDO execution unit 17c outputs the executed restoration content to the REDO information addition unit 17d.

  The REDO information adding unit 17d stores the restoration content received from the UNDO execution unit 17c in the storage unit 14 as REDO information used when the restored data is executed again by executing UNDO. At this time, the REDO information adding unit 17d stores the restored content as the latest UNDO information in the storage unit 14.

  Here, with reference to FIG. 4 to FIG. 6, a process from restoring data to storing the REDO information in the storage unit 14 and a change in execution information stored in the storage unit 14 will be specifically described. FIG. 4 is a diagram showing an example in which UNDO processing is newly executed, FIG. 5 is a diagram showing an example in which information in the storage unit is changed by the executed UNDO processing, and FIG. 6 is executed. It is a figure which shows the example which stores the UNDO process in a memory | storage part as REDO information.

  As shown in FIG. 4, in this example, edit 1, edit 2, edit 3, and edit 4 are executed in order on the file to be edited. In edit 1, editing for net A and editing for part B are executed. Similarly, in editing 2, editing for net C, editing for net D, and editing for part E are executed. In edit 3, editing for net F, editing for component E, and editing for net D are executed. Similarly, in editing 4, editing for net F and editing for net C are executed. Thereafter, FIG. 4 shows an example in which editing 5 is executed, unlike FIG.

  Here, it is assumed that the content executed in the editing 5 is “UNDO processing for returning the part B to the original”. In this case, the UNDO target determining unit 17a determines that the component B is a restoration target, and outputs the component B as an UNDO target to the UNDO information control unit 17b together with an UNDO processing start instruction. The UNDO information control unit 17b reads out the process information management “part movement” of the command information management “edit 1” as the most recently executed UNDO information from among the UNDO information for the part B stored in the storage unit 14. It outputs to the execution part 17c. Also, the UNDO information control unit 17b reads out the editing content associated with the process information management “part movement” and outputs it to the UNDO execution unit 17c.

  The UNDO execution unit 17c executes an UNDO process by executing an operation opposite to the process information management “part movement” of the received command information management “edit 1”. That is, the UNDO execution unit 17c executes a process for restoring the amount moved by the process information management “part movement” of “edit 1”.

  Then, as shown in FIG. 5, the REDO information adding unit 17 d changes the “status” of “post-edit information” in the process information management “part movement” to “deleted from normal”, and changes the “pre-edit information” “ Change "Status" from "Deleted to Normal". That is, the REDO information adding unit 17d sets the status after editing of the component B moved by the editing 1 to “delete” to exclude it from display, and sets the status before editing of the component B moved by the editing 1 to “ Set to “Normal” for display. At this time, the REDO information adding unit 17d stores the restoration contents executed by the UNDO execution unit 17c in association with the process information management “part movement”. As a result, the operation opposite to that of editing 1, that is, UNDO is performed.

  Subsequently, as shown in FIG. 6, the REDO information adding unit 17d adds the editing 5 described above as a new “command information management”, and the “process information” of the component B for which UNDO has been executed by the UNDO executing unit 17c. Correspond with “Management”. As a result, the contents restored by UNDO, in other words, the REDO information can be managed without creating new “process information management” in the storage unit 14.

[Flow of processing by data editing device]
Next, the flow of processing by the data editing apparatus will be described with reference to FIGS. Here, the overall flow of processing will be described with reference to FIG. 7, and the flow of UNDO processing will be described with reference to FIG.

(Overall processing flow)
FIG. 7 is a flowchart illustrating a process flow in the data editing apparatus according to the first embodiment. As shown in FIG. 7, when the control unit 15 of the data editing apparatus 10 accepts the start of editing work via the input unit 12 (Yes in step S101), the control unit 15 reads the target CAD data and starts editing. It is determined whether edit content has been accepted (step S102).

  When normal editing content is received (Yes at Step S102), the editing execution unit 16 executes editing content instructed via the input unit 12 (Step S103). Subsequently, the editing execution unit 16 stores the executed editing content as UNDO information in the storage unit 14 (step S104). Thereafter, the edit execution unit 16 returns to step S101 to execute the subsequent processes until an edit process end instruction is received via the input unit 12 (No in step S105). On the other hand, when an editing process end instruction is received via the input unit 12 (Yes in step S105), the editing execution unit 16 ends the process.

  In step S102, when contents other than normal editing contents, in other words, restoration contents (UNDO contents) are accepted (No in step S102), the restoration execution unit 17 executes UNDO processing (step S106). The process of step S105 is executed.

(Undo process flow)
FIG. 8 is a flowchart showing the flow of UNDO processing. This process corresponds to step S106 shown in FIG. As illustrated in FIG. 8, the UNDO target determining unit 17 a acquires an UNDO processing target from information input via the input unit 12 and determines a target (step S <b> 201).

  Subsequently, the UNDO information control unit 17b sequentially refers to the UNDO information (execution information) corresponding to the UNDO processing target from the storage unit 14 (step S202), and whether or not the referred UNDO information belongs to the processing target net. Is determined (step S203).

  If it is determined that the UNDO information referred to by the UNDO information control unit 17b belongs to the processing target net (Yes in step S203), the UNDO execution unit 17c executes UNDO processing based on the referenced UNDO information (step S203). S204). Thereafter, the REDO information adding unit 17d stores the information related to UNDO executed by the UNDO execution unit 17c as REDO information in the storage unit 14 (step S205).

  On the other hand, in step S203, if the referenced UNDO information does not belong to the processing target net (No in step S203), the UNDO information control unit 17b reads the next UNDO information from the storage unit 14 and executes the process of step S203. (Step S206).

[Management method of UNDO information for each processing target location]
Next, with reference to FIGS. 9 to 12, for example, a management method of UNDO information for each processing target portion described above such as a net unit will be described. FIG. 9 is a diagram illustrating an example of a history of executed editing information, and FIG. 10 is a diagram illustrating an example in which the restored contents subjected to UNDO processing are stored as REDO information. FIG. 11 is a diagram illustrating an example in which editing is resumed after UNDO processing, and FIG. 12 is a diagram illustrating an example in which UNDO processing is performed after editing is resumed in FIG. 11.

  As shown in FIG. 9, in this example, editing 1, editing 2, editing 3, and editing 4 are executed in order on the CAD data to be edited. In edit 1, editing related to net A and editing related to net B are executed. Similarly, in editing 2, editing related to net C, editing not related to parts and nets, and editing related to part 1 are performed. It is running. In edit 3, editing related to net B, editing related to net A, editing related to part 1, and editing not related to parts or nets are executed. Similarly, in editing 4, editing related to net A is performed. Editing related to the part B and editing related to the net C are executed.

  In such a state, it is assumed that the restoration execution unit 17 of the data editing apparatus 10 continuously executes UNDO processing three times only for the net B by a user operation. In this case, as illustrated in FIG. 10, the restoration execution unit 17 restores only the information related to the net B by going back sequentially from the editing 4 that is the latest editing information stored in the storage unit 14. That is, the restoration execution unit 17 restores the process related to the net B of edit 4 as the first UNDO, restores the process related to the net B of edit 3 as the second UNDO, and restores the process related to the net B of edit 1 as the third UNDO. Thereafter, as shown in FIG. 10, the restoration executing unit 17 stores the restored contents executed at each of the first, second, and third times in the storage unit 14 in order after the editing 4 as REDO information.

  Further, it is assumed that the editing 5 is resumed after the UNDO process is continuously executed twice for only the net B from the editing state shown in FIG. In this case, as shown in FIG. 11, the restoration executing unit 17 sequentially goes back from the editing 4 that is the latest editing information stored in the storage unit 14, restores the processing related to the net B of the editing 4 as the first UNDO, and edits 3 is restored as the second UNDO process. Thereafter, as shown in FIG. 11, the restoration execution unit 17 stores the restoration contents executed in each of the first and second UNDO as REDO information in the storage unit 14 in order after the editing 4. After that, the edit execution unit 16 is associated with the edit content related to the net A, the edit content related to the net B, and the net C as the detailed information of the newly executed edit 5 after the REDO information newly stored in the storage unit 14. The edited contents are stored in the storage unit 14 in time series.

  Thereafter, it is assumed that UNDO processing is continuously executed five times only for the net B by the user's operation in a state where the editing 5 shown in FIG. 11 is executed. In this case, as shown in FIG. 12, the restoration executing unit 17 restores only the information related to the net B by going back sequentially from the editing 5 that is the latest editing information stored in the storage unit 14. That is, the restoration execution unit 17 restores the processing relating to the net B of the edit 5 as the first UNDO, restores the processing relating to the net B of the REDO information as the second UNDO, and further performs processing relating to the net B managed as the REDO information to the UNDO3. It will be restored as the second time. Subsequently, the restoration execution unit 17 restores the process related to the net B of the edit 4 as the fourth UNDO, and restores the process related to the net B of the edit 3 as the fifth UNDO. Thereafter, as shown in FIG. 12, the restoration execution unit 17 stores the restoration contents executed in each of the first to fifth UNDOs as REDO information in the storage unit 14 in time series after the editing 5.

[Specific examples of editing and UNDO processing]
Next, a specific example when editing and UNDO processing are executed will be described with reference to FIGS. Here, as shown in FIG. 13, the active component A and the active component B are connected by the wiring of the net A and the net B through a resistor, and the active component C and the active component D are connected by the wiring of the net C.
